To all 'whom t ma concern.' y

Be it known t at I, IsAAoWoonR-ING, a

citizen of the United States, and resident of.

Waverly, in the county ofV Bremer and State of Iowa, have r`invented.' a new and useful Feeding Device for '.Corn-Husking. Machines, of which the following isa specication;V

The object of my invention is to provide A a feeding device for corn husking machines particularly designed for use in canning factories. 4

More particularly, it is my object to provide such a device whereby corn which has beenremoved from thestalks and on which the husks have been left may properly be fed to mechanism fo'r cutting olf the butts of the husks.

A further object is to provide a machine of the class mentioned, provided with mechanism whereby the unhusked corn is fed intoproper receptacles on a traveling oonveyer and then maintained in suitable position and carried past belts. which cut o the'butts of the husks and cobs. f1

, Still a further object' is to provide in such a machine mechanism for regulating the speed at .which the corn is fed to the traveling conveyer.

My invention consists in certain details,

v in the construction, combination and ar-v rangement of the various parts of the device `wl1ereby the objects contemplated are attained, as hereinafter more fully set forth,

pointed out in my claims and illustratedQin the accompanying drawings, in which-.

Figure l shows a top or plan view of a feeding device for corn husking machines,

embodying my invention. Fig. 2 shows a Fig. 3 shows'a front elevation of said machine. Fig. 4 shows av detail, plan view of a portion of the bars or slots which support the cuttingblades. Fig. 5 shows'a detail, sectional view of a portion of the conveyer, showing the contraction of the corn receptacles, and Fig. 6 shows a detail, sectional view of a 'portion n -1 off said conveyer and of said slots .or bars,

,` illustrating the manner in which said bars 0. are adjusted.'

In the accompanying drawings I have -usedthe reference numeral 10 to indicate generallythe frame of my improvedl machine. Mounted at the rear of the frame is 5 a receptacle 11 and adjacent thereto is a traveling convevar- 10, 'Php traveling c011- veyer 12 is. mounted in a suitable frame 13 havmgI at its lower end a Shaft 14 and at its upper end a shaft 15 on which the conveyer 12 travels. Extending downwardly and forwardly in the machine from the upper end of the frame 13 is a platform 16 which is'pivotally mounted in the `middle of Vits forward end' at 17. Upright members 18 are pivoted to the frame-10 and extend* u-pwardly andi are pi'voted at their upper ends to t-he`Y respective- 'sidesof' the upperfendl, o fthe platform 16. 0n the l'atform 161I provide brackets 19' and in'tli receive bolts 21 which are extended throu h earms 18 I pro.-

vide a plurality of' holes 20,- to selectively- 70 the brackets 19- for pivotally securing t e I arms 18 to the platform 16. Connecting the arms 18, near their centers, is a horizontal bar 22, each end of whichy is pivoted to one of the arms 18.

4 It will be noted that'by moving* the bar, 5 Y I 22 longitudinally, the platform 16 may be vibrated from side to side". At the sides of the'platform 16 are side boards or walls 23 which extend from the top approximately to the middle of the platform 16. Hinged to the -lower Eends of the side boards 23 are movable side boards 24. Secured# to the side boards 24 are short angle irons 25 designed to be secured in various positions of the platform 16l by vmeans of bolts 26 selectively received in holes 27 insaid platform.

Mount-ed on the frame 10 is a shaft 28 on which is a belt 4wheel- 29 or other means whereby the shaft 28 may be rotated from a suitable sourceof power. On the shaft 28, at .the front end of the machine, are' sprocket wheels 30. The shaft 28 may be located on the left hand side of the machine, as shown in Fig. 3. At the other side of the machine is a short parallel idlershaft 3l on which are sprocket wheels 32, in line'.

the platform 16 are substantially vertical.

The upper ends of saidside walls, on the other three sides, are flared or inclined outwardly, as shown in Figs. 5 and 6, The chains 33 'and 311 are secured to the sides of the. buckets 35 approximately midway between their tops and bottoms, as 'clearly shown in Figs. 3, 5 and 6. The chains 33 and 34 and the buckets 35 are so located that the upper ends of said buckets travel below the lower end of the platform 16 for receiving ears of cornldischarged from .said platform.

are of sufcient length to carry corn considerably beyond the platform 16. Located in front of the platform 16 and just below the buckets on the 'upper part of the chains are parallel guide strips or boards 36 which are mounted on the frame of the machine in the following manner.

Near the front end of the machine is a transverse angle iron 37 to which are secured a. plurality of brackets38 which are partially supported by braces 39. The brackets 38 are provided with screw threaded openings to receive the screw threadedI bolts 40, the slots of which are firmly secured to the guide bars 36. On the bolts 40, above and below the brackets 38, are nuts 42. The brackets 38 are provided with slots 43.

It will be seen that by `loosening' lthe nuts 42, the position of the bolts 40 in the slots 43 may be changed so that the space between the parallel guide bars 36 may be va'ried.

The guide bars 36 extend slightly .beyond the lower end of the platform 16, as shown in Fig. 3. Secured to the guide bars 36, near their left hand ends, Vas shown in Fig. 4,

are one ormore knives or blades 44, having substantially the shape of a V with the sharp cutting edge in the notch of the V. The arms of the blades 44 are provided with slots 45 to receive bolts 46 whereby the' blades are secured to the bars'36. By loosening the bolts `46, the bars 36 may be adjusted as hereinbefore set forth to -vary the distance between them. Beneath the ife blades 44 is a discharge chute 47. Adjacent to the delivery ends of the guide bars 36 is a traveling conveyer 48 which travels over rollers or shafts 49, 50 and 51.

The upper portion of the traveling conveyer 48 travels from position below the delivery ends of the guide bars 36 rearwardly in the machine and discharges above `a receptacle 52. 0n the shaft 51 is a. friction disk 53 and slidably mounted on the shaft 28 is a friction wheel 54 designed to engage the disk 53. Mounted on the frame of the machine is a transverse shaft 55. y Secured to the ends of the shaft 55 are levers 56 and 57. Pivoted to the lever 56 is a link 58 operatively connected with the friction wheel 54 for sliding the same on the shaft 28. On the 'shaft 51 is a belt pulley 59 and on the shaft 15 is a .belt pulley 60 in line with the pulley 59.. A plate or rod 61 travels on the pulleys 59 and 60. Gn the shaft 28 is a acre/,see

wheel 62. Pivoted to the wheels 62, ofil center thereof, is a pitman 63 which extends upwardly and laterally in the machine and is pivoted to the bar 22.

At each side of the platform 16, near the upper end thereof, is an upwardly extending member 64. Secured to the arm 64 and lt will be seen that the chains 33 and 34v spaced above the platform 16 is a bar 65. The arms64 are provided with a series of openings 66 to selectively receive the bolts 67 by which the bars 65 are secured to said members 64. l

I provide a substantially elliptical frame 68 made of channel bar and arranged adjacent to the upper ends of the vertical sides of the buckets 35. Upon each of said vertical sides are two rollers 69 'which travel in the channel bar frame @68 for holding the buckets in proper position.

In the practical operation of my improved machine, the pulley 29 isnpivotally connect=` ed with a suitableI source of power. lWhen the shaft 28 is rotated, movement is trans.

mitted through the wheels 54, the disk 53, the pulleys 59 and 60 and the belt 61'to the shaft 15 and the conveyer 12. Material in the receptacle 11 is carried to the upper endof the conveyer 12 and discharged upon the platform 16. By means of the wheel 62, the pitnien 63, the bar 22 and the arms 13, a lateral vibrating movement is imparted to the upper end of the platform 16. Corn which. has been :removed from the stalks but on which the husks remain is discharged upon the upper end of the platform 16. On account of the arrangement ofthe bar 65, the ears must rest flat on the platform 16 in order to pass under said bar. On account of the fact that'the butt-end of. the ear is the heavier end the vibratory motion of the platform 16 causes the ears to slide toward the lower end of said platform with their heavy ends downwardly.

1The operator may stand by the side of the machine and assist in arranging the ears as they pass downwardly over the platform 16 and between the lower ends of the side boards 24. The butts of the ears of corn slide over the upper ends of the buckets 35 and the ears drop into the receiving buckets. The lower ends of thebuckets 35 are `open and the heavy end of the ear restsA upon the guide bars 36, as clearly shown in Fig. 6. y

As the buckets pass along, ears are carried 4over the knife blade 44 and the butts are cut Conveyer48 by which they are carried rearwardly'in the machine and discharged into the receptacle 52.

.It will, of course, be seen that the chains 33 and 34 are operated from the sprockets on the shaft 2S and that the conveyer 48 is operated from the shaft 51, the disk 53, the frictionv wheel 54 and the shaft 28.

For accommodating the machine to ears of different weight and thickness .thedistance of the guide bars 36 from each other may be varied by loosening the nuts 42 and sliding the bolts 40 in the slots 43 in the brackets 38.

As has already been seen, the feeding may be partially regulated by regulating the position of the sideboards 24. Thisfmay be clone by removing the bolts 26 and placin them in different holes 27. The height o the bar 65 above the platform 16l may/.be varied by placing the bolt 6.7 in different holes 66. The rear end of the platform 16 may be elevated or lowered by removing too rapidly to be properly fed from the plat-y with his knee while thebohs 21 and placing them in different If, at any time, the corn should be elevated form 16 to the buckets, the operator ma by means of the levers 56 and 57, slide t e friction wheel 54 toward the center. of the disk 53 and thereby decrease the Speed of the conveyer or elevator 12.

In actual practice, the operator standing on the right hand side of the machine, as shown in Fig.. 1, may operate the lever 57 guiding the corn with his hands.-

Many ofthe advantages of my improved `feeding device for corn husking machines may be seen from the foregoing description. It will of course be understood that the corn in the receptacle 52 may be fed to the husking rollers, ras desired. It is well'known that unless the corn is sua pcd close -to the cob when it is removed romthe stalk, it is' much harder to complete thel removal of the husks when thebutts are left on the ear than when they are removed.

I'have found that where my improved machine is used, it is comparatively easy'to 'remove the remaining portion of the husk Cop'ies of this patent may be obtained for ve cents each, by addressing the Commissioner of Intente,

may be .included AWithin appended claims. I

after the butts thereof are cut-off.- fIt will be seen that the cornmay be fed into the vbuckets 35 very rapidly and a very large amount of corn may be trimmed by a single workman operating my improved machine. On account of the method of'operating lt-he elevator 12 the supply of-corn can be accuratelyregulated so that it may be fed to advantage with-out overcrowding the plat-l form 16. r

.It will be understood that changes may be made in the details of theconstruction of my machine without departing from its essential features and it is my purpose by this application to cover any such changes which I claim as my invention: 1. In a device of the class described, a

traveling conveyer, a plurality of buckets mounted thereon' and designed .to receive ears of corn, said buckets being open atvvboth ends, guide bars beneath a portion of the upper part of said traveling conveyer designed to support ears of corn contained in said buckets and a blade ou said guide bars designed to cut oft' the lower ends of said 2. In ar-device ofthe class described, a'-

the scope of the traveling conveyer, a plurality of buckets mounted thereon,"open at both ends, a pair.4

of parallel guide rods under a part `of the upper portion of said conveyer, designed to supportears of' corn in said buckets, a bladey mounted on said bars and means for varying j the distance of said bars from each other. v

3. In a' device ofthe class described, a

traveling conveyer, a plurality of buckets' mounted thereon, open-at both ends, a pair of parallel guide bars mounted beneath the upper part ofsaid conveyer and designed to support years of corn contained in said buckets, la cutting blade mounted on said bars, and means for feeding ears ofnnhusked corn, butts downward, intov said buckets.
